DRAWING-FRAM E.

SPECIFICATION forming part of Letters Patent No. 507,079, dated October17, 1893.

Application filed May 1s, 1893. serial No. 474,657- lNo modem To allwhom it may con/cern:

Be it known that I, JOHN E. BREST, of Whitinsville, in the county ofWorcester and State of Massachusetts, have invented certain new anduseful Improvements in Drawing- Frames; and I hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying. drawings, formingpart of thisspeciiication.

This invention has reference to improvements in machines for drawing outand evening the carded-sliver and delivering the same to the cans.

The object of this invention is tolocate the bite of the rolls directlyover and near the guide-tube of the can to deliver the sliver directlyfrom the delivery-rolls into the guidetube and at the same time toconsolidate and calender the sliver at the nearest approach to theguide-tube.

Another object ofl the invention is to provide a drawing-frame with agravity calendering and guide roll which is adapted to be turned backfrom before the delivery-rolls.

The invention consists in the peculiar construction of the framessupporting the delivery-rolls and the combination therewith of a gravitycalendering and guide roll journaled :in bracket-arms which are pivotedto the delivery-frame rolls, together vwith such other Anovel featuresof construction and combination of parts as may be hereinafter morefully described and pointed out in the claims. Figure 1 represents anend view of adrawlng-frame and the can for receiving the sliver passingfrom the delivery-rolls, showing the improved guiding and calenderingdevice. Fig. 2 represents an enlarged end view of the delivery andcalendering rolls to show more clearly the construction of thecalenderingroll supports.

Similar letters and numbers of reference designate corresponding partsthroughout.

In the drawings 5 indicates one of the standards on which the table top6 is supported. The end-frame 7 is secured to this table top and isfurnished with vertical-slots 8-8 in which the ends of the drawing-rolls9&9 and 9--9 are carried, a similar frame being used to support theopposite ends of the rolls.

From the forward portion of the top 6 extend brackets 10-10 having theinclined members 11-11, in the upper end of which are formed bearings12-12, open at the tops, in which the ends of the upper delivery-roll 13are journaled, and from these bearings extend the perforated-ears 14-14;in the lower main portion of the members 11--11 are formed theconcave-bearings 15-15 in which the ends of the lower delivery-roll 16are journaled, similar bearings being formed in the separable plates17-17 secured to the members 11-11 by-'bolts to support the roll 16 inplace, the trumpet 18 being supported, with its small end adjacent tothe delivery rolls, in any ordinary mannear.

The calendering and guide roll 19 is journaled at the ends in bearingsof the curvedarms 20--20, these arms having the stops 2121 at theirupper ends and being pivoted at these ends to the perforated-ears 14, so

that when swung upward to the position shown in dotted lines in Fig. 1,the stops 21 will come in contact with the back edges of the ears andsustain the roll 19 in the elevated position.

The sliver a-ct passes between the rolls 9-9 and 9-9, then through thetrumpet 18 between the delivery-rolls 13 and 16, being` then directeddownward by the calenderingroll 19 pressing the sliver against the roll16 and consolidating the ber so that it may be coiled in the can 22 bythe coiler 23 in layers which will not intermix but can be readilywithdrawn, or uncoiled, in the subsequent manipulation of the sliver.

The roll 19, journaled in the pivoted arms 20, serves to more perfectlycalender and consolidate the sliver, while it also assists in directingthe movement of the sliver toward the guide-tube of the coiler. Thisroll may be driven by any usual driving-mechanism.

Having thus described my invention, I claim as new and desire to secureby Letters Patent.
